The underestimated role of pest pentatomid parasitoids in Southern South America
TLDR
This review article presents extensive data from the literature on the two main groups of biological control agents referred above, and discusses ways to promote biological control as the most important tactic to manage stink bugs in Southern South America.
Performance of Nymph and Adult of Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) Feeding on Cultivated Legumes
TLDR
Performance of nymphs and adults of Piezodorus guildinii feeding on different cultivated legumes was studied under controlled laboratory conditions, indicating that SIP and AIP are suitable food sources, and emphasize the importance of alfalfa as a host plant of P. Guildinii in Uruguay.
Effect of Photoperiod and Temperature on Nymphal Development and Adult Reproduction of Piezodorus guildinii (Heteroptera: Pentatomidae)
TLDR
These laboratory results suggest that P. guildinii does not reproduce during the time its preferred host soybean is unavailable at latitude 30°–35° S, which corresponds approximately to the conditions tested at 10:14 h L:D (20 °C).
Seasonal occurrence of Piezodorus guildinii on different plants including morphological and physiological changes
TLDR
Results suggest that the control of P. guildinii during spring on alfalfa may reduce the population of bugs before they colonize soybean.
Phenological and Physiological Changes in Adult Piezodorus guildinii (Hemiptera: Pentatomidae) Due to Variation in Photoperiod and Temperature
TLDR
Results indicate that adults of P. guildinii maintained under a short (10 h) photophase at 20 °C enter into reproductive diapause, accumulate energetic reserves (lipids), show undeveloped reproductive structures and smaller size, clear coloration of the pronotum band and connexivum, and less feeding activity.
Seasonal Occurrence of Different Grasshoppers Species (Orthoptera: Acridoidea) in Uruguay
TLDR
To determine the need for control and to avoid irreparable loss, samples must be intensified from early November to the beginning of December, when the young nymphs are no longer predominant.
Overwintering of Piezodorus guildinii (Heteroptera, Pentatomidae) Populations
TLDR
Piezodorus guildinii (Westwood) is a soybean pest that causes significant economic losses in the Americas and its variability was evaluated in populations of the Southwest and Northwest Regions of Uruguay, where female diapause in the SW was longer than that in the NW (mid-autumn to mid-winter).
Earthworms in Agro-Ecosystems of Uruguay
This study assessed the richness and abundance of Oligochaeta in two long-term experiments in Uruguay. In one experiment, located in eastern Uruguay (UEPP, INIA Treinta y Tres) we evaluated four
